I think I'm having an IO load issue:
At night, i have 2 client PC's backing up and the server does its backup.
My server backup failed last night; it stated the D: drive was not ready.
Server backup occurs at 11pm. Clients back up starting around midnight.
Looking at event logs It's almost like I have an IO load issue:

The shadow copies of volume \\?\Volume{2846f327-4c3f-430d-a7ca-c38129a2308c} were deleted because the shadow copy storage could not grow in time. Consider reducing the IO load on the system or choose a shadow copy storage volume that is not being shadow copied.

Server is a HPN54L with the OS on the included HD and my D drive (the one that appears to be having the issue) is on a Western Digital Red, 1TB.
The western digital red is in a storage pool by itself right now.
thoughts?
